The 0.165\" (4.20mm) row spacing matches the pitch, keeping the board layout symmetrical and simplifying trace routing between rows. ## 30 µinch Gold Mating Finish for Field-Service Duty Brass contact material with square pin geometry delivers consistent normal force across the mating interface, maintaining low contact resistance over the connector's service life.","metaTitle":"Molex 0039289248 Mini-Fit Jr Header, 24 Circuits","metaDescription":"Molex 0039289248 Mini-Fit Jr 5566 series header, 24 circuits, 4.20mm pitch, dual-row, through-hole, shrouded, with board lock and locking ramp.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Pin Headers, Sockets & Housings"],"specifications":{"Mfr":"Molex","Style":"Board to Cable/Wire","Series":"Mini-Fit Jr 5566","Features":"Board Lock","Packaging":"Tray","Shrouding":"Shrouded - 4 Wall","Part Status":"Active","Termination":"Solder","Applications":"General Purpose, Industrial, Telecommunications","Contact Type":"Male Pin","Contact Shape":"Square","Mounting Type":"Through Hole","Connector Type":"Header","Fastening Type":"Locking Ramp","Number of Rows":"2","Pitch - Mating":"0.165\\\" (4.20mm)","Voltage Rating":"-","lifecycle_stage":"unknown","Contact Material":"Brass","Insulation Color":"Natural","Insulation Height":"0.504\\\" (12.80mm)","Ingress Protection":"-","Base Product Number":"003928","Insulation Material":"Polyamide (PA66), Nylon 6/6","Number of Positions":"24","Row Spacing - Mating":"0.165\\\" (4.20mm)","Contact Finish - Post":"Tin","Contact Length - Post":"0.138\\\" (3.50mm)","Current Rating (Amps)":"-","Operating Temperature":"-","Mated Stacking Heights":"-","Overall Contact Length":"-","Contact Finish - Mating":"Gold","Contact Length - Mating":"-","Number of Positions Loaded":"All","Material Flammability Rating":"UL94 V-0","Contact Finish Thickness - Post":"100.0µin (2.54µm)","Contact Finish Thickness - Mating":"30.0µin (0.76µm)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$10.0700","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null},"ai":{"faq":[{"question":"What is the pitch of Molex 0039289248?","answer":"The mating pitch is 0.165\" (4.20mm) for both the row-to-row spacing and the contact-to-contact spacing within a row."},{"question":"Is Molex 0039289248 RoHS compliant?","answer":"The part is listed as RoHS compliant per the standard Molex declaration for this series.
